Not to get anyone's hopes up here, I haven't tried it yet. This morning my 6 year old daughter asked if we could get some coconuts and open them. Of course I said yes. So... The question now is how to best open one (preferably kid safe if possible). Will a 4.1 work to crack around the coconut? Should I just let her whack it with a hammer a few times? I could always just use a machete, but that doesn't really let her be involved much. Any suggestions?
